User Guidelines
This command has the following consequences: incoming untagged frames are assigned to this VLAN and outgoing traffic in this VLAN on this port is sent untagged (despite the normal situation where traffic sent from a trunkmode port is all tagged). The command adds the port as a member in the VLAN. If the port is already a member in the VLAN (not as a native), it should be first removed from the VLAN.
Example
The following example e8, in trunk mode, is configured to use VLAN number 123 as the "native" VLAN.
Console (config)# interface ethernet e8
